A kind of ozone decomposition catalyst and its preparation method and application

Abstract

The invention relates to an ozonolysis catalyst and a preparing method and application thereof. The method comprises the steps of mixing a forming carrier with a manganese source solution, after fullwetting, conducing drying, then mixing the mixture with additive, conducting a reaction at constant temperature, after the reaction is completed, obtaining a regular carrier covered with a manganese precursor, and after baking, obtaining a catalyst product, wherein when manganese in a manganese source is at +7 price, the additive is reductant, and when manganese in the manganese source is at +2 price, the additive is oxidizing agent. The catalyst preparing process and the forming process are integrated, on the basis of the forming carrier, efficient manganese-based ozone catalyst is subjectedto in-situ growth on the outer surface of the forming carrier, the catalyst is stably combined with the carrier, the surface of the catalyst is stable, powder does not easily fall off, the particle size is adjustable, the appearance is formed, the ozonolysis capability is also efficient, the ozonolysis catalyst conveniently fills all air purifiers or fresh air system modules, production of an airpurification module can be accelerated, and the application prospect is good.

Description

Technical field [0001] The present invention relates to catalyst preparation and the field of air pollution purification, and more particularly to an ozone decomposition catalyst and a preparation method thereof. Background technique [0002] Ozone (O 3 ) And oxygen (O 2 ) Is a homologous body of oxygen element, and there is a double-edged sword for human dependence. In the same temperature layer, ozone is good for our living environment, it can resist harmful ultraviolet rays; however, in the near-place table, ozone is an invisible killer, which will have different degrees of skin and nervous system, etc. Impact, it can also damage the human immune function, resulting in chromosome lesions in lymphocytes, accelerating the aging of the human body, resulting in an increase in the birth rate of malformation. The World Health Organization stipulates that the concentration of ozone in the 8-hour environment continuous work cannot exceed 0.1 ppm. At present, there are ozone pollution ...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, the ozonolysis catalyst is directly loaded on the carrier by the impregnation method. However, the products obtained by impregnation method tend to have insufficient bonding force between the catalyst and the carrier, and the catalyst is easy to fall off.
